For example, commuting, while not nice most of the time, has one great impact on life: it allows you to break from work, which is not happening when you have sleep/work/hobbies/life at the same place. I'm not saying you should spend 1h in traffic or subway, but 20min and walking would be a great way to change thoughts and separate work from life.
Also seeing your colleagues for real, and spending some time with them, as they are humans, is a great way to have better empathy and better work relations: using only remote tools doesn't provide such a human behavior.
